IMPROVEMENT IN RUBBER HOSE.

Specification forming part of Letters Patent No. 194,363, dated August21, 1877 application filed June 9, 1877.

To all whom it may concern:

Be it known that I, HENRY J. MERRENS, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and and usefulImprovements in Rubber Hose; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawing::, which form partof this specification.

My invention relates to rubber hose; and consists in the new andpeculiar manner ofits construction, as hereinafter fully specified andclaimed.

In the drawing, Figure 1 represents a longitudinal section of hoseembodying my invention. Fig. 2 is a perspective View, showing the mannerin which thecloth, either saturated with rubber or not, is applied. Fig.3 is a similar view representing the cloth in position and secured withcord or wire.

The object of my invention is to make a stronger hose, that shall beless likely to become ruptured, and that can be manufactured at acheaper price than hose of ordinary construction.

The inner portion A of the hose is of rubher, and formed on a mandrel inthe usual well-known manner. Around this is wound a long piece of coarsecloth, B, either saturated or impregnated with rubber or not, somewhatwider than the circumference or distance around the inner portion A sothat one of its longitudinal edges may overlap the other to a greater orless extent, as may be found most effective and convenient. The cloth ispreferably used with the warp running parallel with the length of thehose, as the cloth can be used in greater length, as well as for otherobvious reasons.

When the cloth has been applied in the proper manner, with its edgesoverlapping each other, then I wind around the same cord, wire or othersimilar article, 0, which serves to retltinthe cloth in place, as wellas to considerably strengthen the hose. According to the strength andsize of the hose required, the operation of a layer of cloth and awinding of cord or wire may be repeated several times. After the lastwinding has been completed, if more than one layer is put on, a coatingof rubber is applied to the same, and afterward I vulcanized.

From theforegoing description it will be un- 5 derstood that myimprovement lies in the specific construction of a hose made in alldetails as above set forth, and its merit is dependent upon theadvantage thereon attendant. Thus, it is old to form an inner layer ofrubber, draw a seamless tube over it, apply cement or a vulcanizingcompound thereto, and then wrap with wire, twine, or thread,

after which an outer tube can be formed about it.

a t But my invention consists in, and what I HENRY J. MERRENS.
